	// `background-color`. We cannot use `filter` since that's not viewed as a
	// background color by the browser. Thus, a hack is needed.
	// See https://developer.mozilla.org/en-US/docs/Web/Events/click#Internet_Explorer
	//
	// For IE8, we set solid black as it doesn't support `rgba()`. For IE9, we
	// set alpha transparency for the best results possible.
